SHUTTLE-CHECKING MEANS FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 766,478, dated August 2, 1904.

Application filed June 2, 1904. Serial No. 210,803. (No model.)

To (tZZ who/rt it may crmcern:

in, while its other and upper end is passed Be it known that I, HENRY WVILKINsON, a through a hole 5, Figs. 1 and 2, in a latercitizen of the United States, and a resident of New Bedford, county of \Vorcester, State of Massachusetts, have invented an Improvement in Shuttle-Checking Means for Looms, of which the following description, in connection with the accompanyingdrawings, is a specification, hke characters on the drawings representing like parts.

This invention has for its object the product10n 0t novel and simple means to check and gradually stop the shuttle when it enters the shuttle-box of a loom whereby the speed of the incoming shuttle is gradually yet eflectively reduced.

Figure 1 is a top or plan view of one end of the layof a loom with one embodiment of my invention applied thereto, the shuttle-box being empty and the checking means in readiness to operate. Fig. 2 is a similar view, but showing the shuttle in the box and at the end of its stroke; and Fig. 3 is a rear elevation of a portion of the mechanism shown in Figs. 1 and 2.

The lay A", longitudinally slotted at A Fig. 1, for the staff of the picker P, the shuttle-box having a fixed front wall 6 and a back 1 wall 5 to form a support and stop for the prolongation 6* of the inner end of the binder B, the latter having a swell 7) to normally enter the shuttle-path, the binder-finger b and the protector-shaft having a controlling-spring p may be and are all substantially of usual construction.

As shown in Figs. 1 and 2, the guard or cover plate 6 of the box extends only about half the length of the box, owing to the novel manner in which the outer end of the binder is controlled.

In accordance with my present invention I have shown a bracket 1 bolted to the back of the lay and provided with a rearward extension or ear 2, having secured to or forming an integral part an upright stud 3. A stout spring .s (see Fig. 3) is coiled around this stud, and one end of the spring is secured to the ear, as by passing it down through a hole at thereally-swinging arm 6, fulcrunied on the stud at the top of the spring-coil, the arm being retained in place in suitable manner, as by a cotter-pin 7. The free end of the arm extends forward over the outer end of the binder B, and adepending fulcrum-stud 8 on the arm loosely enters a suitable hole in the binder, the stud S forming a bodily movable or shiftable fulcrum for the binder. A lever is fulcrumed at 9 on the outer end of the lay beyond the end of the binder, one arm, 10, of the lever bent around behind the binder and under the arm 6, an upright pin 11 on the leverarm 10 entering an elongated slot 12 in the fulcrum-carrying arm 6. The other leverarm, 13, extends across the path of the picker P (see Fig. 1) and constitutes a bunter adapted to be struck by the picker when the latter is thrown outward by impact of the incoming shuttle. Alug 14, depending from the bunter, is adapted to engage the end of the lay and limit inward movement of the bunter, the spring x being so wound that it normally tends to swing the arm 6 outward into the position shown in Fig. 1, the swell If of the binder then projecting into the shuttle-path.

\Vhen the shuttle S, Fig. 2, enters the box, it hits the swell, throwing the inner end of the binder rearward, the binder swinging on the stud 8 as a fulcrum and against the action of the protector-spring p; but when the advancing shuttle strikes the picker P the latter is thrown against the hunter 13. The latter moves the picker, while the lever-arm 10 moves in the opposite direction and by the slot-andpin connection with the arm 6 swings the latter in the direction of arrow 15, Figs. 1 and 2, compressing the spring e and shifting the fulcrum-stud S to the right, viewing Figs. 1 and 2. Such shifting of the fulcrum-stud causes the binder B to move bodily and longitudinally in the same direction or opposite to the direction of movement of the shuttle, the friction thus induced between the binder and the shuttle effectually completing the checking of the shuttle and bringing it to a stop, as shown in Fig. 2. When the binder is moved longitudinally, its extension 7) slides to a slight extent along the end of the binderfinger 5 As soon as the picker is moved inward to throw the shuttle from the box the spring s expands, returns the bunter-lever and the arm 6 to normal position, and thereby the binder is moved outward to its normal position in readiness to check the shuttle on the next pick into the box.

The construction is very simple, strong, and durable, and the checking action is very effective without exerting any undue shock in stopping the shuttle.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. Ashuttle-box,aspring-controlled binder, and means to move it longitudinally and bodily by and opposite to the direction of movement of the incoming shuttle.

2. A shuttle-box, a picker, a spring-controlled binder, and means operated by or through impact of the incoming shuttle upon the picker to move the binder longitudinally and bodily opposite to the direction of movement of the shuttle.

3. A shuttle-box, a binder, a movable fulcrum for the outer end thereof, a spring acting upon the inner end of the binder to press the same into the shuttle-path, and means governed by the incoming shuttle to bodily shift the fulcrum and move the binder longitudinally opposite to the direction of movement of the shuttle.

4. A shuttle-box,a spring-controlled binder, a horizontally-swinging, springcontrolled arm on which the outer end of the binder is fulcrumed, and means to swing said arm by or through the incoming shuttle and thereby move the binder bodily and longitudinally in a direction opposite to the movement of the shuttle.

5. A shuttlebox',a spring-controlled binder, a horizontally-swinging, springcontrolled arm on which the outer end of the binder is fulcrumed, and a bunter having a fixed fulcrum and operatively connected with said arm, said bunter'being adapted to be hit by the pickerv to thereby swing the arm against the tension of its spring and move the binder longitudinally and bodily in a direction opposite to the movement of the incoming shuttle.

6. A shuttle-box, a spring-controlled binder slidably supported at its inner end, a bodilyshiftable fulcrum for its outer end, a spring to act upon said fulcrum and normally position it to present the binder in the shuttlepath, and means actuated by or through the incoming shuttle to shift the fulcrum bodily and thereby move the binder longitudinally opposite to the direction of the movement of the shuttle.

7. A shuttle-box, a picker, a spring-controlled, longitudinally-movable binder having a swell normally in the shuttle-path, means actuated by the picker when struck by the incoming shuttle to move the binder longitudinally opposite to the direction of movement of the shuttle, and a spring to restore said means andthe binder to normal position.

8. In a loom, a lay having a shuttle-box thereon, a picker, a spring-controlled, bodily and longitudinally movable binder, a laterally-swinging arm fulcrumed on the lay at the outer end of the shuttle-box and pivotally connected with the adjacent end of the'binder, a spring to move said arm to normal position, and a lever pivotally mounted on the lay and operatively connected at one end with the swinging arm, the other end of the lever constituting a bunter crossing the path of the picker, rocking of said lever when hit by the picker swinging the arm against its spring and thereby moving the binder longitudinally opposite to the direction of movement of the shuttle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HENRY WILKINSON.
